DEVlCE FOR SUSPENDING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 297,133, dated April22, 1884.

Application filed March 4, 1884.

To all whom it may concern:

Be itknown that I, J osnrn D. HUNTINGTON, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements for suspending Machinery, of which the following isa full description, reference being had to the accompanying drawings, inwhich Figure 1 is a side elevation; Fig. 2, an end elevation; and Fig.3, an enlarged detail, showing a spring and the connecting parts insection.

The object of this invention is to improve the construction andoperationof devices for suspending machinery, to prevent vibration and noise, toenable the revolving parts of machinery to find rotating centers, and toimprove the construction of apparatus designed to be used in accordancewith my previous patent, No. 290, 056; and its nature consists in theseveral improvements and combinations hereinafter set forth and claimedas new.

In the drawings, A indicates the ceilingtimbers or floor, to which theupper attachments are made; 13, suspending-rods; G, the frame forsupporting the moving parts; D, bearing-boxes; E, shaft; F,driving-pulley; G, the polishing or grinding wheel; H, undersupportingor suspending bar; I, spring-plate; J, fioorplate; a, springs; b,sockets for the reception of the springs; a, bolt passage or opening;dc, bolts; f, brackets; g h, eyebolts; t, fiistening-bolts; j,set-screw.

The frame 0 in its simplest form is made of cast-iron, as shown in Fig.1, which is a single bar having its ends turned upward to provide forthe bearing-boxes of the shaft E. This frame may also be provided withplates or arms 0, which serve as rests for the article to be operatedupon, or as tool-rests. The boxes D are in the usual form of half-boxes,and are provided with suitable oilers or oil-holes. The brackets f areattached to this frame, as shown in Fig. 1, and at their upper ends theyare provided with recesses or cups for the reception of the end of arubber spring similar to that shown at b in Fig. 3. The eyebolts 9 passthrough the bracket and the spring, as

shown at Fig. 2, a washer and screw-nut being applied to the lower endof the bolt, in order to secure it and to adjust the tension of (Nomodel.)

"the spring. The rods B are attached to the eyebolts g at their lowerends, and to the eyebolts h at their upper ends. The eyebolts it passinto or through the joist, or through a cross-piece attached to thejoist, and they are held by screw-nuts. These bolts It may have springsattached to them at their upper ends, if desired; but ordinarily it willnot be neces sary; and if it is desired to avoid metal contact toprevent noise, these eyebolts g and it maybe lined with soft metal orother suitable material.

As shown, the rods B are provided with eyes at their ends; butinstead ofeyes, hooks may be used, and for ordinary purposes they will besuflicient. The rods B may be made of common round iron, and are usuallymade of this material when hooks are used; but they may be made of Wirerope, chain, or wood, provided with metal ends.

In the form here shown, the frame 0 is supported from below by a singlebar, H, and by preference this bar is made angular or square incross-section, and is attached to the frame 0 by a socket fitted toreceive it and the bolt or pin 1'. At its lower end the bar is attachedto the plate I, which is provided with a suitable socket in the middlefor its reception, and is fastened therein by the bolt 43 and in orderto prevent its turning, I also provide a set-screw, j, which is made topress against the bar, so as to prevent any turning or vibration of therod or machine at its fastenings. A similar set-screw may be used at theupper end; or the bar may be fastened entirely by set-screws, omittingthe bolts 7;.

The plate I is usually cast with the socket for the reception of the barH in the middle and the sockets b at the ends, with a strengtheningflange or fin between the sockets, as shown in Fig. 1. The socket b maybe made of a greater or less depth, according to the amount or portionof the spring it is desired to hold therein, and is provided with ahole, 0, which is larger than the bolt passing through it and thespring, so as to avoid meta-1 contact and prevent noise; and asufficient portion of the spring is placed within the socket to preventlateral vibration or displacement of the bolt. The bolts d pass throughthe opening 0 of the plate I and through the spring a, and

are provided with a collar or washer adapted to fit the end of thespring, and with a screwnut, by which the compression of the spring andthe strain of the bar H can be regulated or adjusted. Two of thesesprings and bolts, as shown at Fig. 1, are sufficient to keep the plateI in position and to prevent it from turning; but for heavy machinery,or where greater certainty is desired, four may be used by locating oneat each corner of the plate.

The floor-plate J is a simple plate made of cast or wrought iron, and isbolted to the floor by bolts 6. This plate J holds thelower ends of thebolts (1 firmly in position, and when it is attached to the floor theframe 0 is suspended between the floor and the ceiling, as shown, andthe bracing position of the rods B and the bar H, being firmly held asdescribed, prevents the frame from turning when any pressure is exertedagainst the side of the wheel G, while it has sufficient play to findits proper center of rotation.

The simple construction of the frame and method of suspending it betweenthe ceiling and thefloor make it a cheap and desirable device for useand for preventing noise and jar; and this method of suspendingmachinery enables me to use machines in buildings where the jar ofmachinery would be injurious; and it also enables me to use them inplaces where otherwise the noise would be a serious objection; and I donot confine myself to the use of these suspending devices with grindingor polishing machinery, as they will be found useful in suspending agreat variety of other machinery; and they can be applied to machineryhaving reciprocating or jarringmovements; and they will take off thejar,so as to avoid the use of large quantities of material, which haveheretofore been used for such purpose.

ever necessary to adapt it to different uses, or u for machines havingreciprocating movements;

and that in some locations the bolts d may be extended through the flooror foundation. so as to make the use of a floor-plate unnecessary.

Vhat I claim as new, and desire to secure by Letters Patent, is

l. The combination of the frame 0 and brackets f with thesuspending-rods B, substantially as specified.

2. The combination of the frame 0 and bar H with the plate I,substantially as described.

3. The combination of the frame 0 and brackets f with the rods B, bar H,and plate I, substantially as set forth.

4. The combination of the plate I, springs a, and bolts (1 with theplate J, substantially as specified.

5. The combination of the plate I, having the recess 1) and enlargedopening 0, with the spring a and bolt (1, substantially as described.

6. The combination of the frame 0 and brackets or yokesf with thesprings a, bolts g, and rods B, substantially as specified.

7. The combination and arrangement of the frame 0, shaft E, and pulleysF with the rods B, single supplanting-bar H, and yielding plate I,substantially as described.
